HEATING SYS'lEIV.

Specification ol' Letters Patent.

Patented April 6, 1909.

Application filed May 23, 1908. Serial No. 434,620.

To all whom 'it may concern:

Be it known that l, FRANK E. BAKER, a citizen of the United States, residing at Oskaloosa, in the county of Mahaska and State el iowa, have invented certain new and useful Improvements in Heating Systems, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in heating systems or plants, and has for its object the provision of means lor economizing fuel and saving heat, by the peculiar construction of the conduits or compartments containing the circulating pipes or tubes.

Anotner object of the invention is the peculiar' construction of a conduit or compartment, which is adapted to receive the prie mary or main circulating pipes, preferably, an outgoing and a return pipe, and also involves the construction ol' a conduit, whereby the main or supply pipes can be easily tapped and new auxiliary or secondary pipes can be attached to supply additional patrons.

W ith these and other objects in view, the invention consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

ln the drawings: Figure l is a longitudinal sectional view ol a conduit constructed in accord-ance with the present invention. Fi 2 is a transverse, sectional view taken on line 2, 2, Fig. l. Fig. 3 is a fragmentary side view el' the conduit and showing particularly one of thc sealing blocks or doors. Fig. 4 is an enlarged detail view of one of the cooks, and showing in section a portion of one of the supply pipes. Fig. 5 is a perspective view of a portion of one el the sections el the clamp. Fig. 6 is a sectional view taken on line 6, 6, Fig. 5.

Referring to the drawings, it is to be understood that my system relates to heating means for a number of buildings or dwellings, which are heated through the medium of, preferably, hot water, supplied from a central station, and which system involves the placing of the outgoing or supply pipe below the return pipe, for the purpose ol minimizing the amount ol heat lost during the outl'low or passage of the het liquid or steam to the subscribers or patrons from the main or central station, and my system involves the peculiar construction of a number el parts or devices of the system or apparatus, and the peculiar arrangement of these novel devices in an operative position., as will be hereinafter fully explained.

Vwreferring to the drawings by numerals, l designates the outer shell or easing or con duit, which may be formed of cement, or any other plastic material that will produce a substantial non-porous rock-like covering, and this conduit is provided with one or more detachable blocks or doors 2, closing openings which are made in the conduit, at predetermined points, for facilitating the connection of new dwellings or buildings to the primary or main supply pipes or tubes. 'he detachable bloels 2 are, preferably, so positioned as to permit the cocks for attaching the new supply pipes to be placed in front of these blocks, as for instance, as shown in Figs. l and 2. Each block 2 is beveled upon its edges for forming a tight joint, and to further facilitate the prevention of moisture from entering` the conduit or escape of heat therelrom, l line the beveled edges el the block, as at 3, 2, with, preferably, tar-paper- 4lllithin the outer cement shell i is placed a plurality of parallel boards 4, which boards are spaced apart at their upper and lower ends by iillingl strips or members 5. rlhe upper horizontal boards 6 are spaced apart by horizontal spacingl strips or members 7, and the lower strips rest upon the top of the inner, vertical boards 4 and the upper edge of the inner top spacing-strip or block 5; the inner strip 6/ is placed between the upper edges oi the inner, vertical boards 4l. At a plurality of places throughout the length of the conduit, there are positioned horizontal transverse strips 8 and vertical transverse strips 9, .vhich divides the spaces between the vertical boards el and the horizontal boards 6 and 6 into a number of closed cells which form air spaces that greatly increases the eli'iciency ol the conduit for preventing heat from escaping as the dead7 or closed air cells loi-m an eilicient non-conductor- Furthermore, it is to be noted that the boards may be lined with any suitable non conducti sheets, as at 10, 2, which sheets or lining may be formed olf tar paper or asbestos, and, consequently, it is within the scope of this invention to provide boards or spaced shells or casings lined with a nonconducting covering, and each casing or shell is spaced apart from the other shells constituting the conduit.

The intermediate, horizontal strips 11 are Yso positioned, preferably, near the center of the vertical boards /1 and the cement outer shell, and extending into these strips 11, and through these vertical boards or inner spaced shells il, are horizontal strips 12. Each supporting strip 12 is provided with a pair of brackets or vertical lugs i3. ln each of the lugs or brackets 13 is journaled a spoolshaped roller or rotatable member 14, which is adapted to receive the return tube or pipe 15, thereby permitting the pipe to slightly expand and contract upon the roller 14 without injuring the same, which roller constitutes the support, together with the horizontal plates or members 12, for supporting the return-pipe 15. it is to be noted that the ends of the horizontal supporting-member 12 is entirely carried by the non-conducting in ner shells constituted by the boards L1, and, therefore, the return pipe 15 is insulated from the outer shell or concrete covering of the conduit, and, consequently, even if the supporting members 12 are formed of metal, and the outer shell 1 becomes moist or very cold the temperature of the pipes will not be affected by being chilled through the contact of the supporting member with said plastic outer shell or covering 1.

intermediate the length of the outgoing or supply pipe 16, there are placed a number of rollers 14a similarly constructed to roller 111, which rollers are in direct engagement with the bottom of the supply pipe 16. Each roller 1era is liournaled upon lugs or parallel extensions 17, and each two contiguous lugs 17, are integral with a base 18; the base 18 being placed upon the bottom of the cement outer shell or covering of the conduit and the bracket, is, preferably, formed of or engages non-conducting material for further insulating the outgoing pipe from the outer shell, for in Fig. 2, l have shown a non-conducting piece of'material 19, as for instance, wood, upon which the roller-supporting bracket rests.

From actual experience, it has been found that the pipes or tubes 15 and 16 travel back and forth as a result of expansion or contraction, due to the heating and cooling thereof, Which, under ordinary conditions, loosens the cocks, causing serious leakage. l have overcome this undesirable feature, by attaching and constructing my cocks 2, in the following manner; l employ, in connecting each cock, a clamp 21, which. holds the cocks securely in position, in addition to each cock being screwed into the supply pipe or tube, as for instance, as shown in an enlarged view in Fig. L1. The screwing of the cock 20 is permitted by means of the depending hollow extension 22, and it is to be noted that the cock is provided with a valve stem 28 for actuating the valve therein. The auxiliary laterally-extending supply pipes 24 are easily threaded into cock or valve casing 20, when desired, for the beveled blocks or doors 2 permit this quick attachnient, as the workmen can easily open the conduit, and by cutting a hole in the block or in the conduit contiguous to the block, the attachment can be quickly made.

` ifhe clamp 21 comprises a substantially U-shaped surrounding band, which has its ends threaded and extended through the horizontal lugs of the upper detachable clamp-member The clamp-member 25 is provided with a body portion having the apertured lugs, through which the upper threaded ends of the surrounding band eX- tend, which threaded ends carry the locking ends for holding the clamp-member 2:3 in a clamped position upon the pipe or tube. The clamping-member is provided, at its center, with a vertical aperture 26, which aperture terminates at its lower end in an enlarged recess 27 within the recess 27 is, preferably, positioned an annular flexible packing 28 that overhangs the walls of the aperture or opening 26, so that when the clamp-member is forced down upon the tube or pipe V(15 or 16) the paclring will snugly engage the threaded extension 22 of the cock or valve casing at the connection between the pipe and said cock or valve casing, and thereby not only prevent leakage, but also materially strengtl'ien the connection and, of c urse, increase the efliciency of the device. it is to be noted that the packing or ring 28 acts as a brace for the reduced threaded extension of the valve casing or cock and, therefore, facilitates the fastening of the casing to the pipe at the opening for the auxiliary tubes.
